The drum 5 is open at the ends and iof SttlliClCllt interior diain eter so that when the deflated tire 8 of the disahled wheel is resting on the ground and the tltltl'fjtltt' wheel is to he attached and is als plated on the ground in proximity to it a -hown in Fig. 2. the huh '3 of the di ahled wheel iua he entered into the open end of the emergent-r wheel but; will he eeeeutrie with the said drum .7 as shown in Fig: '3.

l\u suitahle mechanism may he prorided l'or aetuatillg the sh es. The preferred liltt'lttllllhlll is aa follows: llaeh ol' Said shoes 9 is mounted h means of a serew holt; l-l whieh is radially mounted or journaled in the periphery of the drum 5 the means shown t'or thus mounting the saitlscrew holt heiu; to form the lower end with the re dueed portion l-l whieh passe loosely thr ugh a perl'oration in the peripherv of the drum 0 that it i. tree t rotate therein, an annular .-houlder l5 whirh hears against the law of the peripherv ol' the drum and a nut ll; on the inner end ol the holt to prorent the h lt fr m falling out. A guide rod 14 is at one end stepped in the periphery of the drum .3 and pa ses loosely through an aperture in an ear ll on the shoe 9 and is at the other end seeured he a, pin lb to :1 I'll T of the euiergeuey wheel. This guide .17 allows the shoe 9 to he moved radially with relati n to the drum toward and away Il'rolu it periphenv and guides it in its movement. The holt 13 is threaded loosely into the tapped out aperture in the shoe. By r tating the holt l3. illilFlllUCll as the holtit elt eauuot more in or out, being prevented therefrom by the shoulder 15 and the nut 16. the shoe 5) will ho moved radiallv toward or from the drum as the case may he according to which way the bolt is turned.

r on the drum 5 is hen the parts are originally assembled the shoes should all be adjusted so as to be equally distant from the axis of the drum and thus no adjustment is required at the time of emergency use.

Mounted on the stem of the bolt 13 above the shoulder 15 is a pinion 1 Journaled a large annular gear ring 20, preferably mounted on ball bearings 21. Said gear ring 20 has crown teeth .22 which engage with the teeth of the pinion 19 and has spur teeth 23 which engage with the teeth of a pinion 21 mounted on the crank shaft 25 operated by a crank arm 26 by means of a handle 27. It is thus obvious that by turning the crank '26 the pinion 24 will cause the large gear 20 to revolve, thereby revolving the pinion 19 and turning the screw bolt 13. Said large gear ring 20 engages with all four pinions 19 which are respectively connected with the severalbolts l3 .and all of said bolts 13 will simultaneously move radially with relation to the drum and longitudinally inward or outward as the case may be.

In case it is desired to gency wheel when the come disabled as previously described, the crank 26. will be turned to bring the shoes 9 all well toward the center. The emergency wheel will. then be placed against the outer side. of the disabled wheel as shown in Fig. 2 so that the hub 2 of the disabled wheel will enter into the chamber of the drum 5, the tires of both wheels resting then on the apply the emergrouud as shown in Fig. 2. The shoes 9 are sufficiently thin so that they will pass between two adjacent spokes 28 of the disabled wheel and said shoes are sufficientlyv oft-set from the emergency wheel so that when thus brought into position the recess.

10 of thefork of each shoe will be in radial alinement with the rim at of the regular wheel. The crank 26 will then be turned in a direction to move the shoes radially outward. As soon as the shoes have moved far enough so that the uppermost shoe begins to engage with the. rim of the regular wheel, the continued movement of the crank and radial outwardmovement of the shoe will lift the rim 4 of the disabled wheel until each one of the other shoes also engages with the rim 4 of the regular wheel. It is obvious from Fig. 2 that the uppermost shoe will begin to engage with the rim 4 before any one of the other shoes engages with the rim because while the regular wheel is in its deflated condition and resting on the ground its axis is below the axis of the emergency wheel and the uppermost wheel is nearer to the rim to start with than any of the other shoes. As soon as the uppermostshoe engages with the rim of the defective tire, the continued upward movement of the shoe will lift the disabled wheel until it is regular wheel has be centered with the emergency wheel and all of the shoes are in engagement with the rim of the disabled wheel. As soon as all of the shoes have become tightly engaged with the rim of the regular wheel and the said wheel is lifted into central position as shown in Fig. 3, there can be no further movement of the shoes and the crank cannot be further turned. lVhen the disabled wheel is lifted, the deflated tire will naturally become somewhat rounded out again as shown in Fig. 3, owing to its natural resiliency after the weight has been lifted to relieve the down ward pressure.

Means are provided to lock the large gear wheel so that it cannotturn backward while the emergency wheel is in use. Any suitable means may be provided. The means shown consists of a dog 29 pivoted at 30 to a post 31. mounted on the drum 5 and having teeth 32, one or more as desired, which engage with the spur teeth 23 of the large gear wheel 20, being held in such engagement by a spring 33. These teeth of the dog will ride over the gear teeth while the crank is turning .the gear wheel to set up the emer-. gency wheel, but will prevent backward r0 tation. lVhen it is desired to turn the gear wheel backward to release the emergency wheel the heel of the dog may be depressed by hand against the pressure of the spring 33 so as to lift the teeth of the dog out of engagement with the gear teeth. The emergency wheel when thus secured to the disabled wheel is firmly held in place, as shown in Fig. 3, and both the disabled wheel and the emergency wheel will revolve together on the same axle 1.

As the shoes will all be adiusted concentrically with. the axis of the drum when the emergency wheel is originally assembled, all that the operator has to do when he has oc casion to use thevwhcel is to place it in the proper position with relation to the disabled wheel and then turn the crank until the shoes are all clamped against the rim of the disabled wheel. Thus the crank and shoes obviate the necessity of any separate lifting jack.

lVhile I have described somewhat in detail the method of construction shown in the drawings by which the shoes 9 are moved radially inward and outward, it is obvious that theameans for doing this may be varied without departing from the spirit of the invention. Any suit-able gearing or driving connection may be employed whereby through the rotation of the crank shaft the shoes may be moved radially outward to engage the rim of the disabled wheel and lift it so that it will be centered with relation to the emergency wheel and be thus held so that the weight will come on the emergency wheel which will thereupon serve in place of the disabled wheel.

ltlt) Preferably the crank arm 26 is removable from the shaft 25 so that it may be taken off after the emergency wheel is set up.

What 1 claim is:
